Dead-End Service Capability

Lug design with threaded inserts allows the valve to be installed at the end of a pipeline or used as a terminal valve, providing reliable isolation without the need for additional flange supports.

Independent Flange Mounting Design

Each lug hole is individually threaded, enabling easier installation and removal while maintaining secure alignment between pipeline flanges.

Suitable for End-of-Line Applications

Unlike wafer butterfly valves, Lug Butterfly Valves can withstand full pressure from one side when the downstream pipeline or equipment is removed, making them ideal for maintenance operations.

Enhanced Piping System Stability

The lug-style connection distributes bolt load evenly around the valve body, reducing installation stress and improving long-term sealing reliability.

Easy Maintenance & Replacement

The lug configuration allows one side of the pipeline to be disconnected while keeping the opposite side secured, minimizing downtime during valve servicing.

Low Torque Operation

Precision-machined disc and optimized sealing design reduce friction between disc and seat, resulting in lower operating torque and smaller actuator requirements.

Excellent Shut-Off Performance

Resilient seat or metal seat options provide bubble-tight sealing performance for reliable isolation in water, chemical, oil, and gas applications.

Compact & Cost-Effective Alternative

Compared with traditional gate or globe valves, Lug Butterfly Valve offers a lighter weight, smaller footprint, and lower installation cost while maintaining dependable flow control performance.
